I got my 5 year old Basenji, Jack, from the Basenji Rescue folks in Florida last January, and of course I'm totally in love with him. Yesterday he threw up his breakfast (undigested) a few hours after he ate; I wasn't too concerned. I've had many dogs and I think all of them had such incidents from time to time, and I recall Jack has up-chucked once or twice. But he did the same thing again today. So I called my vet and they said they were overbooked and to just give him some boiled chicken and call on Monday if he's still having problems. He doesn't seem at all sick – normal as can be.
I just now gave him a little helping of boiled chicken with rice, and put in a little calcium cabonate (antacid). He thought it was odd food but ate it happily.
I'm concerned he might have an obstruction -- do Basenji's get hairballs (bezoars) very often? He does groom himself quite a lot; my cats are always upchucking hairballs and they seem to deal with it just fine, but so far I haven't seen much online about whether it's common for Basenjis, and if it will just right itself. Any advice?
